The Atmospheric Mid-Cool Grey
Fog is a perfect name for Glide 10CG6 -- the soft, even, atmospheric quality of grey that reads as ambient and cool rather than warm and textured. At the mid-value position in the Cool Grey series, Fog is the most practically useful of the four Cool Grey thread options: not so light as to be a near-neutral like Cool Grey 3, not so dark as to read clearly as dark grey, but the soft mid-value cool grey that integrates across the broadest range of grey fabrics in modern and contemporary quilts. It is the Cool Grey series equivalent of German Granite in the warm grey family -- the versatile production default.

Where Fog Sits in the Cool Grey Ladder
The Glide Cool Grey series runs CG3 (light) → CG6 Fog (medium) → CG7 (medium-dark) → CG9 (near-charcoal). If your fabric leans warmer, step sideways to Flint or German Granite instead.
Frequently Asked Questions
How do I choose between Fog and Cool Grey 3?
Match thread value to fabric value: Cool Grey 3 disappears into light grey and near-white fabrics, while Fog integrates on true medium greys. If the fabric would photograph as "grey" rather than "almost white," Fog is the pick.
Is Fog warm or cool in undertone?
Distinctly cool -- a blue-leaning grey. On warm greige, taupe, or brown-tinged grey fabrics it will read slightly blue; use German Granite or Flint for those.
Is there a matching pre-wound bobbin?
Yes -- the Magna-Glide Delights line includes matching Cool Grey bobbins, so top thread and bobbin match exactly in colour and fiber for production work.
